Abstract

[Problème] Le problème décrit par la présente invention est de fournir un dispositif de mesure d'informations biologiques capable d'effectuer une mesure très précise en laissant un utilisateur reconnaître avec précision qu'une unité de réception/émission de lumière et un sujet sont en contact à une pression appropriée pour une mesure. [Solution] A cet effet, un dispositif de mesure d'informations biologiques selon un mode de réalisation de l'invention comprend : une unité de réception/émission de lumière comprenant une unité d'émission de lumière qui émet, vers un sujet, une lumière ayant une longueur d'onde prédéterminée, et une unité de réception de lumière qui reçoit de la lumière ayant traversé le sujet; et une unité de notification qui applique une action physique au sujet à une étape prédéterminée à partir du début jusqu'à la fin de la mesure par l'unité de réception/émission de lumière.
